Will crash the next time you open a document The reduction queues up post-attach callback which is not dispatched. When you open another document and it attaches, the callback is dispatched, but its target has already been deleted, and you crash. The way the reduction manages to queue the callback but avoid dispatch is that the body element changes from being in the document to not being in the document during dispatchChildInsertionEvents() in appendChild(). This means that the appended children get insertedIntoDocument() (so the iframe element queues up the callback), but never attached. 9193 3 14708 mitz 2007-05-24 14:56:08 -0700 Created attachment 14708 Simpler reduction for the crash Made the removal explicit instead of using document.write(). To trigger the crash, it is important to close the reduction before opening the new document. 9087 4 14731 mitz 2007-05-26 01:53:00 -0700 Created attachment 14731 Fix for the crash One strange thing that I noticed while making this patch is that the HTMLFrameElementBase methods call up to HTMLElement rather than HTMLFrameOwnerElement, which is the parent class. I followed this practice in removedFromDocument() but I don't understand it. 9075 5 darin 2007-05-26 07:30:44 -0700 (In reply to comment #4) > One strange thing that I noticed while making this patch is that the > HTMLFrameElementBase methods call up to HTMLElement rather than > HTMLFrameOwnerElement, which is the parent class. I followed this practice in > removedFromDocument() but I don't understand it. There's probably no reason to follow that practice. It's just a mistake that needs to be fixed. Are there any cases where it's actually skipping over a function in HTMLFrameOwnerElement? If so, we'd need to study those carefully before changing them. 8976 6 14731 mitz 2007-05-26 08:42:35 -0700 Comment on attachment 14731 Fix for the crash Going to make a new patch. 8981 7 14737 mitz 2007-05-26 09:23:40 -0700 Created attachment 14737 Fix for the crash Corrected the parent class in overrides that call up. Did the same in HTMLPluginElement. HTMLFrameOwnerElement does not implement any of the functions being called. 8892 8 14737 mjs 2007-05-28 23:39:32 -0700 Comment on attachment 14737 Fix for the crash r=me 8866 9 sam 2007-05-29 13:43:13 -0700 Landed in r21862. 8868 10 mitz 2007-05-29 13:54:03 -0700 Another bug is needed to track the "WebKit doesn't show this javascript screenshot page" part of the bug. 75445 11 rjrecio 2008-03-27 04:19:13 -0700 It isn't functional yet, it doesn't crash but after clicking on the screenshot you cannot go back to the screenshot page as works in firefox 75642 12 darin 2008-03-28 09:09:05 -0700 It would probably have been better to use a separate bug report for the non-crashing half. 75643 13 14737 darin 2008-03-28 09:09:26 -0700 Comment on attachment 14737 Fix for the crash Cleared the review flag on tis patch since it was landed. 118044 14 zwarich 2009-04-18 19:48:03 -0700 The problem seems to be giving this error message: TypeError: Result of expression 'd.postMessage' [undefined] is not a function. It seems that this might just be a site problem, looking for postMessage on the 'document' rather than 'window'. 118051 15 rjrecio 2009-04-19 00:04:50 -0700 it's strange because works fine on firefox 118052 16 zwarich 2009-04-19 00:14:57 -0700 There could be some unintended browser sniffing going on. I'll try to take a closer look. The actual problem is in a Google Ads JS file, so it is probably a good idea to figure out what is wrong. 332950 17 ap 2011-01-12 00:34:46 -0800 The site has been redesigned, and the "screenshots don't appear" part no longer happens. 14697 2007-05-24 01:33:03 -0700 2007-05-24 14:56:08 -0700 Reduction for the crash.
